The term secondary environmental impact refers, inter alia, to the environmental impact which may arise if, because vehicles become dirtier, they have to be cleaned more often and this increases the emissions of the vehicle care products. The aim is to find whether winter road salting affects wash frequency, the use of car cleaners and corrosion. Compilation of the responses to a questionnaire shows that there are significant differences in the care of cars between Gotland (unsalted) and the mainland opposite Gotland (salted), and between part of Vaesterbotten county (lightly salted) and part of Vaesternorrland county (salted). If salt application was discontinued, wash frequency would be cut by ca 30 percent and the use of degreasers and screen wash fluid would be reduced by 40 to 70 percent.
